I read that to be a running total of all game margins since 1920. Perhaps I misunderstand, but that's what it says.

edit: I just looked again: yes, that's exactly what it is, and it's a dumb ass graph.
I was making a calculus joke with "integration"
Now I'm upset all over again.
Bah, it's a neat graph to look at. A couple of thing surprised me, how historically bad the Steelers were, and that the Lions, until recently (post 2000) had kept they head above water - I wouldn't have guessed that.
